Specification of Letters Patent.

Application filed February 9, 19117.y Serial No. 147,697.

To all whom t may concern:

Be it known that we, CHARLES B. SCHOEN- MEHL and MARTIN L.V MAnTUs,citizens of. the United States, and residents of Water,

bury,'in the county of New Haven andState of Connecticut, have inventedcertain new and useful Improvements in Primary Batteries, of which the'following'is a specification.

Our invention relates to what are commonly known as cylindrical forms ofprimary batteries employing an active solution contained within acovered jar.

The invention further and particularly relates to a novel form ofsupporting means for both the positive and negative cylindrical elementswhereby the same may be spaced one from the other and readily supportedand suspended within the solution through a single rod or hanger whenattached to the cover of the jar; to include means for preventing theadhesion to the under side of the insulative member of the disintegratedportions of the elements and whereby the electrodes might becomeshort/circuited further to arrange and construct the parts so as toafford a practical and rigid assemblage ofthe several'parts-of thedevice so as to permit the same to be commercially manufactured in aneconomical manner, to construct the device so that amplecontact isprovided with the respective elements to insure a proper and economicalworking yelements themselves, thus permitting renewals to be made,furnished and attached at a comparatively small expense.

Upon the accompanying two sheets of drawings forming apart of thisspecifica-V tion similar characters Of reference will be found toydesignate like or correspondingparts throughout the several figuresyand of which- Figure 1 shows a central' vertical' section through ourimproved form of battery com-y plete.

Fig. 2 is a detached plan view of the assembled elements as containedwithin the jar shown in Fig. 1 and clearly illustrating a top view ofthe insulative supporting member to which the electrodes are attached.

Fig. 5 shows an inverted detached planv view of a slightly modified formof the insulative support for the elements, and y Fig. 6 shows acentral( vertical sectional view of an assembled element including aninsulating block like that shown in Fig. 5

and having two negative electrodes.

Referring in detail to the characters of refeience marked upon thedrawings 6 in-v dicates a battery jar and 7 a. cover both of which maybe of the usual or any pre ferred construction and in which the assentbled elements together with the active solution are contained. y

8 represents the insulative supporting member which as will be noted isof a generalv annular forni and to the under side of which the severa-lelectrodes are attached. Outwardly disposed extensions 9 are formed onthe outside of this supporting member. The positive electrode 10 issecured to the underside of this extension and in a way to leave anopening 11 between the said body ofthe supporting member and the saidelectrode, thus better exposing the electrode to the action of thesolution.

Inwardly exposed extensions 12 are formed upon the inner side of theannular supporting member to receive the inner annular positive element13 and also in a way to form openings 14 between the supporting memberand the top edge of the positive elementV as is clearly shown in Fig. 2.

Patented Mar. 18,1919.`

rlhe positive electrode-s may be formed of either cast or rolled zincand each is pro'- vided With metal. hangers which may be formed in anypreferred manner, as for instance, a piece 15 attached to the body ofthe positive electrode as shown in Fig. 3, or cast integral therewith,as shown at 16 in Fig. 4. The construction of the hanger as employedupon both the inner and outer positive electrode may be substantiallyalilre in construction and are each provided with a hole through which ascrew bolt 17 passes in its method of securing 'the tivo like electrodesto the supporting member and in its further purpose of electricallyconnecting the two like electrodes. rlhese scren7 bolts, as Will benoted, are arranged radially and central of the supporting member so asto be entirely insulated from the negative element. Both of the screws17 thus serve to engage the tivo positive elements 10 and 13 in a mannerto rigidly secure the same to the insulative supporting member andwherebyy both of the said elements may be detached by the removal of thetivo screws. The terminal Wire 18 is preferably attached to one of thesescren7 bolts and in practice extends up through a hole 19 of the coverfor connection to the circuit Wire (when a jar with a cover is used).

The negative element which is designated as 2O is of a cylindricalformat-ion and in practice is also secured to the insulative supporting`member S and intermediate of the tivo positive elements, forming anannular receptacle that is preferably filled with oXid of copper in anyof the usual forms. The inner side Wall Q1 is preferably made ofperforated sheet inet-al7 vvhile the outer surface is similarly7 coveredby a sheet of Wire screen Q2. lf he ends of the cylinder asavell as theinner and outer metal protective coverings are engaged by annular xapsQ3 which further serve to hold 'the negative element in position andprevent it from flaling aivayas chemical action takes place. Thisnegative element is supported to the under side of the insulative memberby tivo vertically disposed hoek like rods 2l which pass throughsuitable holes in the iusulative supporting member and entend doventhrough and along the 'inside of the cylindrical negative eilem'ent andhave their extreme lower ends turned out and upward to form a supportfor the lower end of the negative element Which is engaged thereby. Theupper ends of the rods are threaded and provided With nuts 25 by meansof which the rods are drawn `up and the elements clamped against theunder side of thesupportingmember 8.

U pon the under side of the insulative supporting member are formed aseries of depending tapered or Wedge shaped ribs 26 and '27, 'which arepreferably arranged as between the points of attachment of the sevanemieVuill readily drain doivn the sides of these ribs and drip from thepointed lou'cr end thus cleaning` the sides with each insertion oyremoval from thel solution.

To these tivo roes 21.1 is also secured the yoke 28 Which crosses theopening through the insulative supporting member, there being formed ineach end of the said yoke t hole through which the rods are passed andivhcreby the nuts when attached are immediately secured dovvn upon thetop and flat surface of the said yoke.. A further hole is formed centralof the said yolre and intermediate of the end portions to receive thesupporting rod Which is provided with a. nut 30 whereby the yoke isclamped against the head of the supporting rod. A nut S1 is attached tothe rod 29 .beneath the cover so that when the rod is carried up throughthe cover it can Vbe properly secured thereto by means of the outer nutthat. finally clamps the several parts together and insures the rigidsupporting of the assembled element to the cover and at a properdistance therefrom so as to be buried ivithin the solution of the TheWinged nut obviously serves to secure the field yvire 34 to the post.

ln liigs. 5 and G We have shoivn our improved insulating support adaptedto support foiuannular electrodes` `tivo of which are positive and tivonegative. The insulatu ing` support in this form is 'ilwn'eferablyprovidedl upon its under side with additional circular ribs locatedbetween the clertrodcs and 36. The fourth 'electrode as employed in thiscase is located central of the element and as ivill be notedj is in' theform of a small perforated basket 3G that is filled ivith oXid ofinet-al to form the second negative electrode. T his instruction forms amore eiiicieut battery as it includes lefr-cater areas of Workingsurfaces. The yokefiZSa in this forni includes extensions 28h that aredisposed upward and are provided with hoors 8C to engage the top edge ofthe'battery4 `yar which has no cover. The second negative element inthis form is electricallyv connected ivith the element Q0 and its yokethrough the hanger by rod 3T,

This feature of tivo cylindrical forms of positive elements and tivocylindrical forms of negative elements being a separately novel featureyit will form the subject matter of ay separate patent application to .betiled later. A
